CORPORA- 'IION, F CLEVELAND, OHIO, CORPORATION OF OHIO MEASURING nnvrcn FOR'MILK rownERs Application filed November This invention relates to measuring devices for milk powders and the like, its object being to provide a very simple and sanitary device for accurately measuring and transferring to the standard nursing bottle a proper charge of powdered infants food or the like, without possibility-of contamination either of the food powder or of the bottle, and which requires no particular skill for operation.

it is necessary to measure a definite quantity in proportion to the amount of water in which it is dissolved. Tablespoons are notoriously inaccurate measuring devices and some manufacturers have supplied shallow cups or other similar measuring devices, but

in all such cases the food receiving surfaces of the measuring cup, as well as the powder in the can or carton, are likely tobe contaminated by the fingers. It is also difficult to introduce bulk milk powder from such a measuring cup into the standard nursing bottle through its comparatively small.

Briefly stated, the device comprises a 4.0 measuring tube which can be plunged into the bulk milk powder in a can so as to become filled with an accurately measured quantity of the powder, and which tube is provided with an extension serving as a handle for its manipulation for so taking up a charge and also as a guide for an ejecting plunger which is actuated with the tube inserted into the neck of a nursing bottle for introducing the charge thereinto, the tube being arranged to j V thisdevice knows, that by retracting the 100 r closely fit the neck and to be supported there- 7, 1927.

upon, andits extension preventing any likelihoodof contamination of the bottle neck by the hands in the act of ejection.

The device'shown for the purpose in the drawing comprises a simple plain tube 1,

whlch maybe made of any suitable material, capableof sterilization, such as glass or the like, although an aluminum tube is quite suitable. Atits ejecting endit is plain and nntlireaded, while at its opposite end it has simple threads, shown as external, to red ceivea cap 2 which may be knurled or roughened at 3 and which has in its end wall an opening through which slides the shank or stem st. of the ejecting plunger. This shank or stem may be a round rod but is shown as a fiat metal strip, to the ejecting end of which is riveted or otherwise secured a plunger head 5. i j v i .The parts are so arranged as to limit the; 'i0 possible motion of the plunger head 5 in the tube 1. In its ejecting movement'it reaches the forward positionshown in full linesFig. 2,'just beyond the open forward end of the -tube, so that complete ejection ofall food powder is secured. At its other limit of .fretracting movement the plunger head 5 oc- .cupies the rear position shown in dotted lines and the volume of the tube cavityfor chamber in advance ofthe head in this retracted po-; g0

Means is therefore preferably pro vided to definitely limit the plungercm'ovement and preferably some means which operates without special attention on the part of the operator, such as the teats or projections 6' punched out from the flat surface of the, metal strip fl, and arranged to engage the vwallpf the cap 2. These projections also permanently secure together as one unit the plunger and the cap 2, so thatwhen the cap ,is unscrewed from the tube there' are only two parts to be cleanedor sterilized.
